Iifayibha zeBasalt zonyusa ukumelana neCarbonation kwiKhonkrithi
I. Indlela yokusebenza yokulwa ne-carbonation: ukulungiswa kwentsebenziswano enamanqanaba amaninzi
1. Ulwakhiwo lwe-Pore kunye nokuthintela iintanda
Iifayibha zeBasalt thintela ukuqhekeka kweplastiki kwangoko kwikhonkrithi (ububanzi obungama-30%-50%) kwaye uvale iindlela zokusasazeka kwe-CO₂ ngokusasazwa kwe-mesh enobukhulu obuthathu. Iimveliso zokufunxa amanzi ezixineneyo ezenziwe kwi-fiber-matrix interface zinokunciphisa umlinganiselo wee-pores ezinobungozi (>100 nm) ukusuka kwi-18.6% ukuya kwi-12.3%, nto leyo enciphisa kakhulu ukuvuleka kwamanzi.
2. Ukuguqulwa kwamanzi kunye Ikhemikhali ukusebenzisana
Uburhabaxa bomphezulu wefayibha bukhuthaza i-CSH gel heterogeneous nucleation, ikhawulezisa impendulo yokufunxa amanzi, iqondo lokufunxa amanzi kwiintsuku ezingama-28 linyuke nge-8%-12%. Xa lidibene ne-mineral admixtures (umz., i-silica fume), isiphumo somlotha wentaba-mlilo kunye nesiphumo sokunciphisa ukuqhekeka kwefayibha sinciphise i-porosity iyonke nge-40%, kwaye umlinganiselo wee-pores ezingenabungozi (
II. Ubunjineli kunye neenzuzo zoqoqosho
1. Ubomi bendlela buye banda kakhulu
Ukwenza okuphezulu I-Basalt Fiber ikhonkrithi ye-asphalt ephandwe yaza yaphuhliswa yiYunivesithi yaseYangzhou, ukumelana ne-rutting kunyuke ngama-20%-40%, ukumelana nokuqhekeka kokudinwa kunyuke ngama-2-8 amaxesha, umjikelo wolondolozo wolulwe ukusuka kwiminyaka emi-3-5 ukuya kwiminyaka emi-6-8, ukonga iindleko zolondolozo lwexesha elide kuncitshiswe kakhulu.
2. Ukusebenza okuphuculweyo kwekhonkrithi ephinde yasetyenziswa
Uphando lubonisa ukuba xa ikhonkrithi ephinde yasetyenziswa (i-RAC) ixutywe neefayibha zebasalt eziyi-2 kg/m³, ubunzulu bekhabhoni buncitshiswa yi-41% xa kuthelekiswa nekhonkrithi eqhelekileyo ephinde yasetyenziswa, kwaye ukuxhathisa kwekhabhoni okungcono kakhulu kufumaneka ngesantya sokutshintshwa kwekhonkrithi ephinde yasetyenziswa eyi-50%.
III. Iindlela Nemingeni Yexesha Elizayo
1. Uphando lokudibanisa oluneendawo ezininzi
Kufuneka sihlolisise ngakumbi ukusebenza kwexesha elide phantsi kokudibanisa ityuwa kunye nomthwalo we-carbonation-chloride, idatha yokuqala ibonisa ukuba izinga le-carbonation yekhonkrithi yefayibha elingaphantsi kwe-0.5 ngokuphindwe umthwalo wokugqibela lisephantsi ngama-28%.
2. Ukudibanisa ukujonga okukrelekrele
Ukufakelwa kwe-optical fiber kunye nenethiwekhi yefayibha eqonda i-carbonation, ukulandelwa kwexesha langempela kwe-carbonation front (ukuchaneka ± 0.1 mm), ukubonelela ngenkxaso yedatha yokugcinwa kokuthintela.
Ifayibha yeBasalt Ibonelela ngesisombululo samanqanaba amaninzi sokumelana nekhabhoni yekhonkrithi ngokusebenzisa ukulungiswa kwesakhiwo se-microstructure kunye nokuphucula ukusebenza kwe-macro. Ngokuphuculwa kwenkqubo esemgangathweni kunye nophuhliso lwetekhnoloji, ukusetyenziswa kwayo kuya kwandiswa ukusuka kwiindlela kunye neebhulorho ukuya kubunjineli bezolwandle kunye nezinye iinkalo, okukhuthaza ukuqina kweziseko zophuhliso ukuya kwixesha elitsha.
